Patented Aug. 19, 1941 UNITED STATES PATENT OFFICE PACKING George T.Henderson, Sandusky, Ohio, assignor to The Binde & Bauch Paper CompansnSandusky, Ohio, a corporation of Ohio Application April 8, 1940, SerialN0. 328,552 V ICI. 206-46) 3 Claims.

This invention relates to a reinforced packing case for packaging andshipping various articles of commerce and particularly intended for usein the furniture trade, whereby a corrugated board carton may beemployed for packing such pieces of furniture er articles in the box insome definite and fixed position. F01 instance, the piece of furnitureor article may be so located in the case that all finished surfaces arefr-ee from contact with the sides cf the case, and such articles as needto be supported off I;he bottom and cut of contact with the Walls andtop cf the case may be so supported. Davenports, chairs, and tables aresome examples cf such pieces although these articles are merelyexemplary since the invention is applicable to various other articles cffurniture. The we ight cannot be allowed t rest on the 1egs because ofpossib-ility of damage to the legs and to the furniture frame generally,and also because concentration of Weight on the corrugated board a1:four small spots is undesirable. Various expedientg are now employed tofores'tall this danger; for example one common means is to use a woodframe or saddle er other built-in structure cf wood er fiberboard underthe frame; or very thick pads cf corrugated board a-re bui1t up from thebottom of the case 110 the cross bars of the furniture to take theweight off the legs, and so on. One cf the chief disadvantages lies inthe fact that these prior deviceg are not sufficiently flexible to beused for a. variety of different; articles. Furthermore some previousmethods require a difiereno size bcix for each different sized article.Y

This invention aims to provide an interior support especially adapted tobe used in 1arge as wel1 as sma1l cases, particularly those made cfcorrugated board or similar materials, to avoid the difficultiesoutlined above. The invention is also particularly applicable as a topand bottom strengthening element in such packing cases, either With orwithout another such support intermediate the height of the case.

An example of a preferred embodiment of the invention is illustrated inthe drawing and described in detail below, it being understood that theinvention may be used in other forms applying the same principles, allwithin the scope cf the claims.

In the drawing:

Fig. 1 is a perspective view of a case 1:0 Which the invention isapplied, the outside being partly broken away 120 Show the interiorbetter;

Fig. 2 is a transverse vertical section on plane 2-2 cf Fig. 1, showinga davenport in dotted lines therein; and

Fig. 3 is an enlarged vertical section on plane 33 of Fig. 2 omittingthe davenport.

The case shown in Fig. 1 is one suitable f0r a davenport II, shown indotted lines in Fig. 2 only, and comprises a corrugated board structureI2 having a top closu-re conventionally shown aus consisting of innerpart laps I3 at the ends and outer abutting half laps I4 at the sides,the joint of which may be taped according to th-e present practice,although the tape i-s not shown. The bottom closure is alsoconventional, and may conveniently be a repetition cf the top.

My invention is shown applied 8;s a supporting brace at; 20 and as a topbrace at 2I. The members are attached the Same way in both instances,and could be cf identical construction, although in the presentembodimeni; slight difierences are illustrated between 20 and 2I.Crresponding reference characters, distinguished .by primes, are usedfor corresponding parts. End bars 22 and 25 are placed horizontally andedge up in corresponding inner and outer positions agatinst Walls suchas the ends 23 of the case I2. The inner bar-s 22' have slats 24fastenecl to their upper edges at appropriate spacing, a.s many slatsbeing used as may be needed, anal the length being enough 1:0 make asnug fit in the case. When the brace i-s in place the outer bars orclamps 25 are applied outside the respective end Walls, opposite theinner bars 22, and. fastened by screws 26 which pass through the endWalls into the bars, Fig. 3. The screws are sei; up tight enough topinch the corrugated board material cf the ends 23, as shown in Fig. 3.The arrangement is the same at both ends. Although wood is illustratedas the preferable material for my improved brace other materials ofconstruction, such a.s metal and bolts, are within the purview of theinvention.

By reason of the clamping action, forces applied to the brace' in anydirecti0 n are distributed over a wide area of the case wall both insideand cutside, and a tight and extensive frictional hold 1s given, Whichis aided by the shouldering effect on the corrugated board be1ow theclamplng bars, in addition to some support by the screw shafts throuehthe Wall 23.

A davenport II is indicated in dotted lines in Fig. 2 showing how suchan article is placed With its frame 30 supported on the brace 2I'I,which is spaced at a height from the bottom of the case I 2 to clear thefeet from the bottvom. A chair er other article could be packed insimilar manner.

of course islacing the supports et suitab1e height. It will beunderstood by those skilled in the art that to hold such articleentireiy clear of the Gase Walls the furniture could be secured to thes1ats 24 by screws 0r bolts iiito the underside 01 the furniture.

When place-d at the top of tne case es 21, at the proper height 170bring the slats 24 at the closing leve1* of the t0p, the bracestrengthens the top and. safeguards tops of large span from bing brokenin, as may occur when other freight is piled thereon. sufficient to useonly one s1at 24' at the top instead of two, in which event the immerand. outer bars 22' and 25 Will be mskterially sherter', for

example the length of the cerresponding lower pieces 22 and 25. Ifconsirlered necessary, a brace, inverted, may be used ina similar manner120 offer protection I01 the bottom cf the case.

By my invention one size of carton can be used to packe variety o1difierent si zes 01 articles, thus reducing the numoer ofdifferergtsizes cf cartons that must be carried in stank by th8 -shipper01 manufacturer. A still iurther advantege is that the strips 25 011 the0utside 0f the box provide excellenthandles making it unnecessary to cuthand hqiesin-the box, apply metel er rope handles 01 the like, and tha/tL-y such handles the support during carrying Qiflfl handling istransmittecl -directly 130 the article rather than through the Walls ofthe cqntainer. v

Inasmuch as the top brace f2 1 srts the clos ure laps, such brace niakes-it possible 130 cement the 1aps I3,E shut insteed of using-tape erspecial stitching:mechines, whieh are ex e ensive than the i.is'e cfedhesive. In additien, adhesive sealing results in a much more rigid boxtop b-ecause the inner andouter laps arte bondeci together overextensive areas, whereas when sealed W'1th tape er stitching there is acertain amount cf weaJving er- Wrackin 0f the box top resulting frommovement between the immer and outer laps.

lt Will be seen irom the foregeing tha-t I have invented apacking-cievice which is adapted te be used in corrugated beard am} likeca1tons of all sizes, and is .particularly advantageeus in lauge sizecases, which requires 110 modifxcation. ef ordinary carton shapes; Whichcgmbines strength,

simplicity, ch zipness ease of application and great stvength;v Whichdistributes tl1e lcad anal es avoids concentrated stresses; which canreadily be removed and .re-used; Whih may easily be made with simpletools; requires 210 sp'ecial skill for its assembly; may b e made in avariety of detailed shapesarid sizes; and. w'nich presents F01" thissituation it is usuaily other benefits and advantages as Will beapparent to those skilled in the art.
